I HALFDAN C. THOMSEN,

AssIGNoB. or oms-FOURTH To CALKIN G DEVICE.

To all whom it may concern:

Be it known that I, WILLIAM ERICKSON, residing in the city and county of San rancisco, State of California, have invented certain new and useful Improvements in Calkf ing Devices, whereof the following is a specification.

lThis` invention relates more particularly for raising the iron free from the oakuni on its return stroke.

The apparatus also includes means by which the stroke of the iron or its penetration 'into the seam may be controlled. This feature and others which enter into the invention will be fully set forth in the subjoined description and more particularly defined in the claims at the end hereof. i

In the accompanying two sheets of drawings I have illustrated an apparatus containing my invention in its best form.

In these drawings: Figure 1 is a plan view of my invention showing the end of the pneumatic` cylinder with the calking iron; the guide portion of the latter being broken away to more perfectly illustrate the interior construction. Fig. 2, is a side view 0f the same with the oakum guide in section and also the attaching rings by which it lis connected to the cylinder. i Fig. 3, is a side elevation of the apparatus. Fig. 4, is a 1ongitudinal section of the automatic cylinder showing the piston and the calking iron in elevation. Fig. 5, is a perspective View showing the end of the cylinder and the calking iron and oakmn guide and connections. In this figure a modified form of spring is shown for causing the calking iron to engage the oakum after the return stroke and at the beginning of its forward stroke. Fig. 6, is a sectional elevation of the same; and Fig. 7, is a front end elevation.

In .these gures 1 represents the pneumatic cylinder ;-2 is the piston reciprocating therein and 3 is 'the calking iron operated thereby and serving to drive the oakum intol the seam to be calked.

At the end of the cylinder 1, attached thereto by rings 4 and 5. and side arms 6 is Sp ecicaton of Letters Patent.

Application tiled November 19, 1913. Serial No. 801,991.

a. shieldand oakum guide 7, through which the oakum 8 is fed. The shield 7 is pivotcd at 9 to the ends of' the side arms so as to be capable of limited oscillation thereon, said oscillation being at right angles to' the seam to be calked.

At 10 is a finger, one on each side of the oakum guide pivoted at 1l and extending forward toward the seam. The oakmn 8 is fed in at the rear of the guide along the calking iron 3, as clearly shown in Fig. 2. The iron 3, being driven forward bythe pneumatic cylinder engages the oakum below the pivot ll, and drives it under the fingers 10 into the seam. In doing this the calking iron 3 passes under thefingers 10 raising their free ends which drop again when the widest portion of the iron has passed them. On the return stroke the iron then rides up over the fingers, which free it from the oakum until it is retracted back of the pivotal pin 11 when it drops down from the fingers against the oakum and is ready for a new forward stroke..- To insure this drop of the iron upon the oakum the spring 12 is provided which tilts up the back end of the shield as seen in Figs. 2 and 3.

The fingers 10 may be provided with `springs (not shown) to depress their free It' desired a spring 13 shown in Fig. 5, may be appl1ed to the calking iron 3 and depress its edge, the iron being pivotcd at 1-1 for the purpose. `It is immaterial which of these two means is employed as the movement necessary is a relative Inovement of the iron 3 and the shield 7.

15 is a pilot wheel which may run along the seam to be calked and guido the yhood and together with the flange 16 hold it accurately in position.

The ring or collar 5 is provided with an oblique slot 17 which is engaged by pin.18 upon the end ofthe cylinder 1. The mrpose of this construction is as follows: The operator holding the cylinder in one hand and the shield guide and its connections in the other, by a. slight twisting movement can cause the cylinder and calking iron 3 to advance or recede relatively to the shield 7, and thereby drive the tool deeper or less deep into the seam.

Instead of fingers l0 above described I may use springs '19 shown in Figs. 5, 6 and Having thus described my invention and l believing l have produced useful and novel improvements 1n the art to which it appertains, let it be understood that I do not Wish to be limited to the. exact arrangement of the several parts composing the same as many changes can be made Without depart-- ing from the spirit thereof, but- That I claim and desire to secure byj` United States Letters Patent is: y

l. ln a pneumatic hand calking tool, in combination with the iron, a guidefor directing the oalrum toward the seam and means for holding said guide in position and cause the iron to engage said oalrum.

2. ln a pneumatic hand calking tool, in combination with the iron, an automatic ad: justable guide for directing the oakum into the seam and holding itin position to be engaged by the iron and means for moving the iron laterally away from the oakum on its return stroke.

" 3. ln a pneumatic hand callringy tool, in combination with the iron, a cylinder therefor, a guide for directing the oakumto the seam, bars projecting from said cylinder for holding said guide'in position and a pilot wheel connected to said bars for guiding' said guide along the seam.

4. ln a pneumatic calking tool, in c0mbination with the iron,a guide for directing the oakum to the seam and fingers pivoted at their rear ends andhaving their forward ends depressed, the calking 'iron passing under said iingers on its driving stroke and over them on its return stroke.

5. ln a pneumatic calking tool in combination 'with' the iron, a cylinder therefor, a guide for the oakum and means 'for changingthe projection of said guide from the cylinder whereby the depth of the drive ing is gaged.

{3.- ln a pneumatic callring tool, in combination with the iron, a cylinder therefor, apguide for oakum mounted upon bars eX- teuding from the cylinder, collars supporting said bars upon the cylinder, one of said collars having an oblique slot, and a pin upon the cylinder engaging said slot.

7A in a pneumatic callring tool, in combination with the iron7 a guide for directing the oalnun to the seam, a device for holding the iron against the oakum'on its driving 94A seam callring tool comprising a shield for holding the material to be driven into the seam, an iron for driving said material, a guard plate above said iron and means for operating said iron. between said shield and said guard plate.

10. A seam calking tool comprising al spring actuated shield for holding the material to be driven into the seam, an iron for driving -said material, means for operating said iron and means forl regulating its driving depth.

11. A seam calking tool comprising a shield for holding and guiding the material to be driven into the seam, a guard plate for covering said shield and an iron operating between .s'aid shield and guard plate for driving said material.

- 12. A seam calking tool comprising a spring actuated shield for guiding thematerial to be driven into the seam, an iron for driving said material and means for causing said iron to engage said material upon said shield.

i 13. A seam calking tool comprising a pivoted guiding shield for the material to be driven into the seam, an iron forv driving said material and spring means for causing said iron to engage said material.

1l. A seam calking tool comprising a pivoted guiding shield for the material to be driven into the seam, an iron for driving said material and means for changing the position of said guiding shield and causing said iron to engage Vsaid material upon said shield.

15. A seam calking tool comprising apivoted tilting guiding shield for the material to be driven into the seam, an iron for driving said material and spring means for causing said shield to tilt. n

16. A seam calking tool comprising a guiding shield' for directing the material to be driven into the seam, and a pivoted iron adapted to engage said material upon said shield and drive the same into the seam.

In testimony that I claim the foregoing l have hereto set my hand in the presence of Witnesses, this 1st day of Nov. 1913.

WILLIAM ERICKSON.
